ABSTRACT
Lesson study is a teacher research process, and focusing on the research aspect helps create more meaningful and deeper opportunities for teacher learning. The chapter illustrates how to align three key aspects of the lesson study process – (1) research lesson goals, (2) lesson problem and (3) student learning data collected during the lesson – to ensure successful research. By presenting examples and cases, the author shows where to pay attention at each stage of the lesson study to purposefully create the alignment among the three aspects, to help teachers learn more about student learning. The chapter also includes an example of misalignment so that readers can understand the challenges of creating close connections among the three aspects, to think deeply about their own practice. The chapter also provides additional opportunities for the readers to think about important mathematics education topics, such as procedural versus conceptual learning, and open-ended problem solving.
